I recently enabled comment moderating because I occassionally get someone posting a comment that has nothing to do with my post (see the first comment under UFO below); they are just ranting about some idea or notion that they want to bombard people with.
I'm all against censorship, but everything has it's time and place. And my blog, my place, is not someone's podium or soapbox. Therefore, if you wish to express you theories, ideas or comments about anything other than my post, kindly do it elsewhere.
Blogger is free; get your blog and leave mine in peace.
